Unfortunately, I was diagnosed with periodontitis (a chronic infection in the gums that starts to affect the teeth) last year and my dentist said to stop using hard brushes to allow my gums to start to heal. These are PERFECT! Bamboo is naturally antibacterial, and I needed that in a toothbrush with my condition. The bristles are soft and rinse easily, the handle comfortable and I love the convenience of the large pack and the numbered brushes. If you're buying for a family, this is great to keep track of which person has which number. For me however, it's great to not have to buy new brushes every 4 months. I just grab another one from my pack. Highly recommended.
